Fuel Gauge
Metric
English
When the ignition is on, the fuel
gauge shows how much fuel the
vehicle has left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
The gauge will first indicate empty
before the vehicle is out of fuel, and
the vehicle should be filled soon.
Here are some situations customers
may experience with the fuel gauge.
None of these indicate a problem
with the fuel gauge.
. At the gas station, the fuel pump
shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The gauge goes back to empty
when the ignition is turned off.
If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
